Nascom/Lucas Nascom (U.K.)

Before the Sinclair ZX80, there was the Nascom 1. It was an inexpensive, Z80-based computer kit sold primarily in the U.K. Unlike the ZX80, it came without an enclosure. Owners had to buy or build a case. A more capable Nascom 2 followed the original model.
Lucas bought Nascom, and in 1982 introduced the Nascom III, a more polished system with a keyboard and enclosure.
